This Wasp Didn't See Her Shadow Either

This morning when I stepped out of my shower I was greeted by a peeping tom. In this situation it's good that it was a wasp that was unannounced and uninvited in my bathroom rather than another human, making this perhaps one of the few times that it's nice to have a wasp in the house.

This is her, groggily climbing the wall next to my bathroom window.

What was she doing there, and how do I know that it was a she? The latter question is simple to answer: it's a she because mated paper wasp queens that were hatched during the previous summer and fall are the only ones who survive and hibernate through the winter. That also answers half of the former question, what was she doing in my bathroom: every year a few paper wasps will choose the roof vent of my bathroom fan to hibernate in, resulting in some of them becoming confused and entering my house through the fan by mistake when they begin to wake up as spring approaches (a couple of nice, warm winter days can sometimes confuse them and prompt an early emergence, too).

The next thing that typically happens is that I find these lost wasps hanging out around the very same window where I found this one today. The reason is that this window faces east, which puts it in just the right spot to catch the morning sun. Like many flying insects, European paper wasps use the sun to navigate and for warmth, so in an enclosed space like a house they will tend to gravitate toward sources of natural light. Most of the time this means they travel to eastern and southern-facing windows, the areas of a structure that get the most light first and longest. Once they get that far and are stopped by the glass, they tend to stay put. They can be easily swatted at this point, or if left alone they will die of dehydration eventually.

I decided to take this picture of my royal visitor this morning and post this tale because chances are that if I am seeing this happening around my house now, people around the Walla Walla valley and beyond probably are, too.

When you see insects begin to appear around your house as spring approaches, like this wasp, it usually means that they have been in some part of the house all winter long. They could be anywhere and have emerged from hundreds of possible entry points, but most of the time they'll simply head for spots where they perceive sun and end up dying there. When it comes to wasps like my visitor, there's not much you can do about them, but fortunately there's also not much to worry about: at this stage, these wasp queens will be very sluggish, and in general because they represent the future of their species they will not be aggressive. They have everything to lose at this point, so random attacks on humans (or anything else for that matter) are not at all on their "to-do" list.

Preventing the springtime appearance of European paper wasps in your home (also insects like boxelder bugs, brown marmorated stink bugs, and some spiders) is actually primarily a fall pest control endeavor. Treating the outside of a home during the fall when many insects seek out winter hibernation spots helps to keep their numbers down by placing an insecticide in their path such that they will be intercepted and killed when they come around to inspect your dwelling.

That's not so say that absolutely nothing can be done about them being in your home now, but just as food for thought the next time fall approaches. If you feel that you have an extraordinary number of paper wasps, boxelder bugs, etc. appearing in your home or office right now, I'd be happy to help as much as I can.

Walla Walla Valley Current Pest Features and 2014 Previews

Over the last couple of days, the Z Pest phone has been ringing more and more as we haltingly move closer to spring time. Here's a short list of the things you can expect to see in the coming weeks that most often bother Z Pest customers, most of which can be dealt with at prices ranging from $40-$65 (plus tax), in rough order:

Odorous House Ants

Though on most days it's still a bit on the cold side as far as ants are concerned (and me, for that matter), the recent retreat of the snow we had around the Walla Walla valley has been followed by waves of ants emerging indoors from hiding places; specifically, it's everybody's tiny friends, the Odorous House ant ("OHA" for short). Or maybe it's just that ants get cabin fever, too. In any case, they're in your home and/or office and you're probably thinking that they have to go.

I can definitely help. But before I head on over, there are a few things you can do to help yourself and me:

1. Don't spray the ants! Most over-the-counter insecticide sprays, even the ones labeled for ants, contain what are known as "repellent" insecticides. They will kill whatever ants you can see, but it's the ants you don't see that matter the most: the queens (unfortunately, that's plural because OHA can have multiple queens in each colony). The surviving worker ants will smell the repellent insecticide and simply avoid that area, and the unaffected queens will continue to crank out eggs. What's worse, sometimes the ants will react by splitting up their colony and spreading out all over your house! Leave any spraying to me, as I use non-repellent, slow-acting products that will reach into their nests.

If the bait you're using works, this is how OHA will react.

2. Baits are ok! Not all baits are equal when it comes to OHA, as some are definitely better than others. What I tell people as a rule of thumb is that if the bait comes in a solid form, the ants are probably going to ignore it. Generally, a liquid form bait will perform better, and as far as over-the-counter baits go, Terro is the one I recommend you use for minor ant incursions. I use something different that avoids some of the flaws of baits like Terro, but it will at least get the ball rolling in the right direction for you.

3. Don't worry about cleaning! I know this can be a difficult thing for some to do, especially when a guest is going to be visiting your home. Let me assure you that after witnessing the chaos generally referred to as the "freshman dorm experience" at Washington State U., seeing a bit of clutter doesn't phase me. That said, I'm not saying that mountains of belongings and trash don't matter, as that would negatively affect my results, but your kitchen counter tops do not need to be squeaky clean just because I'm coming over. The reason cleaning can actually make things a bit harder for me when I come to treat your ants is that you may inadvertently remove the thing the ants were interested in, which in the case of OHA will cause them to go back into hiding. That doesn't make treating them impossible, but it can make it a longer process.

Spiders

Spiders maintain both an indoor and and outdoor presence, and some species live up to a couple of years, which prompts them to spend winter indoors with us. The vast majority of spiders that you encounter in your home, office, and yard are NOT potentially harmful (physically, that is), and the species folks around here most commonly fear, the dreaded brown recluse spider, doesn't even live in this part of the United States!

This is a mother wolf spider that briefly lived with me, with
her newly hatched babies riding on her back.

Spiders you will commonly see around here are brown house spiders, jumping spiders, various types of orb weaving spiders, and swift little grass spiders. On occasion, you may encounter black widow spiders, but these shy, non-aggressive spiders will typically stay as far away as they can from you as you will from them.

During the winter months, I can help you reduce or eliminate populations of spiders inside your home or office with some simple crack, crevice, and spot spraying with appropriate pesticides. During the spring, summer, and fall, I mostly address spiders with exterior treatments (which can reduce or eliminate the presence of spiders indoors the following winter). If your home or office has a crawl space, I can also treat those spaces with insecticidal dusts that will provide even more long-term control of spiders (typically for six to eight months).

Boxelder Bugs

It's still a little on the cold side most days for our local six-legged sunbathers, but they are already making occasional appearances (as of the date of this writing, I've already performed one boxelder bug treatment for a customer this year).

Boxelder bugs sunning themselves on the side of
a building belonging to one of my clients.

Though harmless to humans and pets, boxelder bugs are nonetheless extremely annoying as they mass in the hundreds or even thousands on the sides of our homes and offices. During the winter months, they wedge themselves into whatever cracks and crevices they can find (under siding, behind rocks, even into the cracks of old telephone poles!) where they wait for the return of spring. They can also commonly be found under gravel, bark beds, piles of leaves, etc.

Treating boxelder bugs is a simple matter of placing residual insecticides on the spots where they are likely to hang out, with emphasis on their preferred harborage areas. To get an early start on them, I can do a crack and crevice treatment around your home and a landscape spray on certain areas of your yard with long-lasting insecticides that will reduce their numbers early on in the season. If it gets to be later in the season before you decide you've had enough of them, no problem, as they can be addressed after they've emerged, too.

Weeds

This is my front yard a few weeks after I treated it.
 I use the same stuff around my own home
and yard as I would around yours!

As soil temperatures slowly trend upward, several weed species will begin putting down roots and pushing up shoots. Others that began their life cycle in the fall months will come out of their slumber and finish up before summer sets in by producing the seeds that will restart their cycle when fall comes again.

Depending on the type of weeds you want controlled, be they in your lawn or your driveway, generally they can be stopped in advance with an application of "pre-emergent" herbicide products. If the weeds have already begun growing, such products can be combined with "post-emergent" herbicides to stop them in their tracks and help prevent more from following.

Z Pest is equipped to handle both large and small weed control jobs with hand-held and truck-mounted equipment. In many cases, these services can be scheduled along with other offered pest control services, which can potentially save you some money.

European Paper Wasps

These terrors of the eaves of your home are still a few months away from becoming a nuisance, but when their time does come again, they can be most effectively dealt with in the early days of their spring and summer life cycle.

These are hibernating European paper wasps
that I found in a crate belonging to one of
my clients last winter. These wasps were
destroyed before they ever had a chance
to become a problem!

An invasive species from overseas that arrived in the United States in the early 1980's, the European paper wasp begins each season with the establishment of new nests by fertile queens that were hatched the previous year. They've spent the winter tucked away in sheltered places, waiting for warmer weather to come out and seek nesting sites.

Generally, these new queens are going to seek out eastern and southern-facing locations that offer solid surfaces to anchor a nest to. They do this to maximize their exposure to sunlight, which they require to warm their bodies. They will also tend to favor locations with accessible building materials (untreated wood - fence posts are a commonly used resource), water (your lawn sprinklers will provide plenty), and soft-bodied insect foods for their larva (any plants in your yard that harbor aphids will attract these wasps, for example).

Because the existence of entire future nests of European paper wasps depends on the success of these awakened queens, that is the ideal time to strike. Treatments around your home with long-term residual insecticides will kill these queens as they investigate your property as a potential nesting site, ensuring that dozens more wasps that each of them would have produced will never exist over the following months. As soon as you spot the young queens taking to the air, it's time to hit them. Give me a call when they do, I'll be ready.

There are plenty of other pests that Z Pest control can address for you in addition to these: earwigs, fleas, mice, birds, etc. Whatever it is that's giving you trouble, give me a call and I'll help you with it as best I can!

Treat Overwintering Pests Now, Have Fewer in the Spring

These are European Paper Wasps, overwintering inside of a storage container belonging to one of my clients. 

These wasps were cold and largely unresponsive to my presence, but they were very much alive. They were clustered together on the side of this box that faces east, the eastern and southern sides of structures being the locations that will receive the most sunlight, be warmest, and therefore harbor the most overwintering pests. Had I not hit the wasps with an insecticide, they would have been the seeds of many new nests (and thereby many more wasps) in the spring.

I took this picture to show that even though it is winter and many pests are not immediately noticeable, they are indeed still present. At this time of the year, pests like these wasps are particularly vulnerable, so addressing them now goes a long way toward significantly reducing their numbers come spring and summer. If you have a "buggy" home in the warm months, I can help you reduce that with focused exterior crack and crevice treatments with long-term residual insecticides now.

European Paper Wasps: The Battle for Your Backyard!

It is once again the time of the year when these unwelcome guests begin to make themselves known around your home or business:

This is the European Paper Wasp, an invasive species in these parts that really puts the "invasive" in the term.  Right now they're flying around all over the place, looking for suitable sites to build nests. Their preference is for eastern/southern exposed areas with nearby food (shrubs and trees that harbor aphids are a favorite), water (yours and your neighbor's sprinkler systems), and a nearby source of raw wood they can take strips from to make paper (got a wooden fence?). These things put together ping this wasp's instinctual radar, and you will find them calling your home their home year after year.

Before you completely tear down your home and reorganize it to make it less appealing to these wasps, try giving me a call! Well-timed and properly placed insecticide treatments can greatly reduce the presence of these pests in your yard, restoring it to its proper function: your enjoyment. I've been ruining the party for these wasps for years, and it's something that I enjoy doing. Give me a call at 509-540-7946 and ask me to come by for a free quote. You won't regret it, but the wasps will!

New Radio Ad, 1490 KTEL Walla Walla

Just did this one on Tuesday the 6th and it hit the air the following day:



There's a primary focus on weed issues in this one, but like the ad says, I take care of insect, rodent, and other issues, too. The weather is FINALLY turning nice again, and that's when the kinds of problems I handle start to appear more often, too. Give me a call, let me help you sort them out, and your home and yard will be for your enjoyment, not some pest's. 

Paper Wasps

I got rid of several batches of these critters for a client recently:

These are European Paper Wasps, a flying insect with a particularly painful sting, but (thankfully) a fairly mild demeanor. Most of the time they'll leave you alone if you leave them alone, but left untreated on your house or in your yard, they can get out of hand quickly. As their numbers rise, so does the chance that you'll cross paths with one or several, and that's when the stingers come out! Fortunately, they're easy to get rid of and with regular follow-up treatments they can be kept away. If you need help with these, please call! 509-540-7946.
